Title: Motor-driven fuel pump for car
Inventor: HIRATSUKA KO
IPC: F04D5/00
Filed: 1985-02-20
Abstract: PURPOSE:To improve the efficiency of pump by making the dimension of diameter of the pitch circle of a high-pressure pump chamber having a labyrinth seal construction smaller than the dimension of diameter of the pitch circle of a low-pressure chamber, and reducing the axial load applied to an impeller in said pump chamber. CONSTITUTION:During the operation of a pump, each pressure on both the low-pressure side and high-pressure side works as a surface pressure load, applying forces which press each other in the axial direction, to the both surfaces of an impeller 5. In order to balance these forces, a pitch circle diameter 18 based on the center of the shaft 9 of a vane part 12 on the high-pressure side is made smaller than a pitch circle diameter 19 based on the center of the shaft 9 of a vane part 11 in a low-pressure chamber. Thus, by reducing a pressure receiving area on the high-pressure side, the forces applied to the impeller 5 on both low-pressure side and the high-pressure side are equalized, reducing axial load applied to the impeller 5 in the pump chamber to improve the efficiency of pump. Furthermore, a labyrinth seal 13 provided on the high-pressure side prevents fuel from leaking from the high-pressure side to the low-pressure side, preventing the lowering of efficiency of pump.

Abstract: PURPOSE:To aim at improvements in labor-saving promotion and operation efficiency, by making a lot of tubular bodies insertable into each insert projection automatically as well as in a short time, in case of a device that inserts these rubular bodies into the insert projection on a mounting block and feeds them to a surface treatment unit for plating or the like. CONSTITUTION:In time of operation starting, first each of cylinders 25a and 25b is extended into motion, while each piston rod is made to come into contact with the lower part of a vibration frame 3 and, after this frame 3 is horizontally supported, a lot of tubular bodies are set on a line-up arrayal plate 1. Next, these cylinders 25a and 25b are moved into contraction, then a vibro-driver 16 is set in motion, and the vibration frame 3 is vibrated. With this constitution, each tubular body 1 on the line-up arrayal plate 1 is forced into rolling motion and entered into the inside of each hole 2. Then, a cylinder 24 is moved into contraction, tilting the frame 3 downward and, after residual tubular bodies 1 are discharged by way of a door 6 in a state of being opened, a shutter 9 is opened by a cylinder 8 whereby these tubular bodies are made to drop down all together and inserted into an insert projection 26' on a mounting block 26.

Abstract: PURPOSE:To prevent a control lever from vibrating extremely during traveling, by adding a concentrated mass to a servo rod. CONSTITUTION:A concentrated mass 8 is added to a servo rod 1 which is not interlocked with a control lever 4 at a speed changing operation time. Consequently, the bending primary resonance frequency of a linkage is freely changed without making the shift operating force heavy and being accompanied with a fear of gear dropout and is set to a value residing outside of the practical rotation range of an engine or a value residing within a rotation range, where the vibration level of the engine is low, to prevent the control lever 4 from vibrating extremely during traveling.

Filed: 1985-02-19
Abstract: PURPOSE:To perform a stable rotation drive operation without using a special position detector by detecting the position by a terminal voltage presented at the input/output terminal of a current to 3-phase coils. CONSTITUTION:The terminal voltages of 3-phase coils 3a-3c of a brushless DC motor is detected by a position detector 11.
